With this configuration, a cooling cycle of the refrigerator 1 according to an embodiment of the present invention will be described with reference to FIG. 5 as following.

When the refrigerant of a gas phase which is compressed by a high temperature and a high pressure at the compressor 3 is flowed into the condenser 4, the condenser 4 condenses the refrigerant of the gas phase in the high temperature and the high pressure into the refrigerant of a liquid phase. The liquefied refrigerant is depressurized through the first capillary duct 5 to be flowed into the cooler evaporating part 27. Then the refrigerant is depressurized through the second capillary duct 6 to be flowed the freezer evaporating part 26. Herein, the converting valve 7 selectively converts the pathway of the refrigerant to the cooler evaporating part 27 or the freezer evaporating part 26. At this time, the refrigerant is flowed into the left side auxiliary evaporating part 28, since the freezer evaporating part 26 is connected with the left side auxiliary evaporating part 28 by the refrigerant moving pipe 50, so that the freezer evaporating part 26 and the left side auxiliary evaporating part 28 generate the cooling air by heat exchange with the freezer 14 and the left side auxiliary storage room 17 respectively. Similarly, the refrigerant is flowed into the right side auxiliary evaporating part 29, since the cooler evaporating part 27 is connected with the right side auxiliary evaporating part 29 by the refrigerant moving pipe 50, so that the cooler evaporating part 27 and the right side auxiliary evaporating part 29 generate the cooling air by heat exchange with the cooler 15 and the right side auxiliary storage room 18 respectively. After that, the refrigerant cooling each storage room is again flowed into the compressor 3.

With this configuration, the process that the evaporator and the duct are assembled in the freezer 14 and the left side auxiliary storage room 17 will be described as following.

First of all, a worker separates the freezer separating partition 21 from the main body cabinet 10 so that the freezer 14 and the left side auxiliary storage room 17 are connected. In case the freezer duct 31 and the left side auxiliary duct 41 are disposed at the main body cabinet 10, the freezer duct 31 and the left side auxiliary duct 41 are separated from the main body cabinet 10.

Then, the worker installs the freezer evaporating part 26 and the left side auxiliary evaporating part 28 which are integrally formed, at the freezer 14 and the left side auxiliary storage room 17. At this time, an inlet 26 a and an outlet 26 b of the freezer evaporating part 26 are connected to an outlet side of the converting valve 7 and the connecting refrigerant duct 8 by a welding and the like. The freezer evaporating part 26 and the left side auxiliary evaporating part 28 are fastened to the inner casing 11 receiving the freezer evaporating part 26 and the left side auxiliary evaporating part 28 by screws and the like. The freezer duct 31 and the left side auxiliary duct 41 formed integrally are coupled to the front of the freezer evaporating part 26 and the left side auxiliary evaporating part 28, and then the freezer branch duct 33 is assembled in the upper part of the freezer duct 31. At this time, the ventilating fans 35, 43 are respectively disposed at the freezer duct 31 and the left side auxiliary duct 41 to be adjacent to the freezer evaporating part 26 and the left side auxiliary evaporating part 28. Alternatively, the ventilating fans 35, 43 are disposed at the inner casing 11 to be adjacent to the freezer evaporating part 26 and the left side auxiliary evaporating part 28 respectively.

Finally, the worker couples an one end of freezer separating partition 21 to the coupling part 77 of the freezer duct 31 and the left side auxiliary duct 41 which are integrally formed, and seats the other end thereof on the seating part 78 formed at the inner casing 11 of the main body cabinet 10 and the main partition 19, thereby completing the assembling.

Therefore, the freezer evaporating part 26 and the left side auxiliary evaporating part 28 are integrally formed with the one refrigerant pipe, thereby being connected with each other. After the freezer evaporating part 26 and the left side auxiliary evaporating part 28 integrally formed are disposed at the freezer 14 and the left side auxiliary storage room 17, only two point of the inlet 26 a and the outlet 26 b of the freezer evaporating part 26 are weld, thereby enhancing efficiency of work in comparison to four point welding in case of the conventional refrigerator.

Similarly, the process that the evaporator and the ducts are assembled at the refrigerator 15 and the right side auxiliary storage room 18 is the same with the foregoing case.

The inlet 26 a and the outlet 26 b of the freezer evaporating part 26 are connected to the outlet side of the converting vale 7 and the connecting refrigerant duct 8 by the welding and the like.

In the foregoing embodiment, the freezer duct and the left side auxiliary duct are integrally formed, alternatively, is detachably coupled.

In the foregoing embodiment, the cooler duct and the right side auxiliary duct are integrally formed. Alternatively the cooler duct and the right side auxiliary duct may be detachably coupled together.

A manufacturing method of a refrigerator having a first storage room and a second storage room to be divided with the first storage room and respectively cooled, the method comprising: providing an evaporator having a first evaporating part and a second evaporating part to be apart from each other to respectively cool the first and second storage rooms, and a refrigerant moving pipe connecting the first and second evaporating parts; providing a separating partition detachably coupled with the main body cabinet to divide between the first and second storage rooms; disposing the evaporator at the main body cabinet so that the first and second evaporating parts correspond to the first and second storage rooms in a state that the separating partition is separated from the main body cabinet; and disposing the separating partition at the main body cabinet to divide between the first and second storage rooms.
 11. The manufacturing method according to claim 10, wherein the first evaporating part and the second evaporating part, and the refrigerant moving pipe are formed with one evaporating pipe without joints.
 12. The manufacturing method according to claim 10, further comprising disposing a separating tray at a space of the first and second evaporating parts to prevent cooling air generated from the first and second evaporating parts from being mixed each other.
 13. The manufacturing method according to claim 12, further comprising: providing a duct detachably coupled inside the first and second storage rooms; and disposing the duct at the main body cabinet so that the duct is mounted to a front of the evaporator.
 14. The manufacturing method according to claim 13, further comprising providing a coupling part supporting a rear end part of the separating partition on the duct.
 15. The manufacturing method according to claim 14, further comprising providing a seating part in a front area of the main body cabinet placed between the first and second storage rooms to support the front end part of the separating partition.
 16. A refrigerator comprising: a first storage room and a second storage room to respectively store food therein; a first evaporator and a second evaporator to supply cooling air for the first storage room and the second storage room, respectively; a separating tray positioned between the first evaporator and the second evaporator to separate the cooling air supplied to the first storage room and the second storage room, respectively.
 17. The refrigerator of claim 16, further comprising: a refrigerant moving pipe to connect the first evaporator and the second evaporator to each other, and to flow refrigerant therebetween.
 18. The refrigerator of claim 16, wherein the first storage room and the second storage room are divided in a vertical direction.
 19. The refrigerator of claim 17, further comprising a first duct and a second duct corresponding to the first storage room and the second storage room, respectively, to supply the cooling air supplied from the first evaporator and the second evaporator into the first storage room and the second storage room, respectively.
 20. The refrigerator of claim 19, wherein the first duct and the second duct are integrally formed together.
 21. The refrigerator of claim 19, further comprising a separating partition to divide the first storage room from the second storage room, wherein the separating partition is detachably coupled with the first and the second duct.
